单项选择题

Many current criticisms of the role of computer and multimedia technology in the school stem from an inability to grasp the nature and importance of computer literacy and to understand how new technologies can help revitalize education. This failure to embrace new technologies as a teaching device has been preceded by an uneven and never adequate use of film and television material in the classroom. So-called "media" material was often used as a supplement, or as an excuse for the teacher to take a break from the arduous activity of interacting creatively with students, and is still used in this way.

It appears as if a form of elitist blindness has emanated from far too many of the leading educational theorists and so-called experts regarding the significance and importance of recognizing the enormous role of media in the everyday lives of both teacher and student. There is also a pervasive failure to employ these common and shared materials and media in a manner that intensifies and enhances the experience of education through teaching about the semiotic (符号) codes and ideological frames that organize and structure so much of media culture. Further, there is a general failure in developing critical skills and analytic abilities that empower both teacher and student, providing them with the skills to analytically criticize and interpret media culture. Moreover, critical media literacy in the computer era is necessary for understanding and navigating within ever more complex technological/ideological forms that require computer and multimedia literacy so as to enable students to utilize computers, CD-ROMs, the World Wide Web, and the Internet.
